Can somebody recommend me an effective way (except ...

Whenever I had a sore throat, I did this immediately upon feeling the symptoms:  Take an eight ounce glass, and pour in one finger's width of apple cider vinegar...then add cool, not cold water to within an inch of the top of the glass.....now gargle the entire glass, one sip at time, of course!!! do this about every 3 to 5 hours, and by the end of the day, your sore throat will be GONE...the vinegar is antibacterial.....yes it'll taste funny, but just keep in mind what it's doing for you; getting rid of the darn sore throat!!! do it first thing in the morning, again in the afternoon, or if you can't, do it in the morning and then as soon as you get home from work......it works!!!

As counterintuitive as it sounds, eat hot pepper products.  It won't burn your throat.  The  capsaicin (the ingredient that makes the pepper hot) kills pain and it will improve your circulation and stimulate your immune system so you'll get better faster.  It also gets rid of flem.

I know of this informational website

Lysterine cures all kinds of nasty things in the throat and mouth. You can put some in a spray bottle and squirt it in your mouth and on the back of your throat, or gargle with it. It tastes terrible, but works great!
